[srsran-users] Working with USRP N310

[ChunChih Lin]

Hi all,

I'm trying to establish srsRAN with two USRP N310 devices, one for EPC+eNB
and the other is for srsUE.
My srsEPC and srseNB are launched successfully, but my srsUE can not attach
to the eNB.
As I dig into the source code, I notice that the "peak_value" which is used
to determine the slide energy is always below the threshold.

I have used uhd_fft as the spectrum monitor to see the signal from eNB and
is shown below.

The signal strength seems to be strong enough, and I can not figure out
what I do wrong.

The attachments are the configuration files and log files for epc, enb and
ue.

Many thanks
